When welding on a machine that is equipped with an

the following procedure must be followed. This
procedure provides the minimum amount of risk to
the electronic components.
Illustration 5

3. Connect the welding ground cable as close
as possible to the area that will be welded.
Components which may be damaged by welding
include bearings, hydraulic components, and
electrical/electronic components.
4. Protect the wiring harness from welding debris
and from spatter.
5. Weld the materials by using standard welding
methods.
NOTICE
Do not ground the welder to electrical components
such as the ECM or sensors. Improper grounding can
cause damage to the drive train bearings, hydraulic
components, electrical components, and other components.
Clamp the ground cable from the welder to the component that will be welded. Place the clamp as close
as possible to the weld. This will help reduce the possibility of damage.
1. Stop the engine. Turn the keyswitch to the OFF

Exchanging Injectors
Exchanging injectors can help determine if a
combustion problem is in the injector or in the
cylinder. If two injectors that are currently installed
in the engine are exchanged between cylinders,
the injector trim files can also be exchanged. Press
the “Exchange” button at the bottom of the “Injector

injectors that will be exchanged and press the “OK”
button. The tattletale for the injectors that were

i02290263
System Configuration
Parameters
SMCS Code: 1901
System configuration parameters are parameters
that affect the emissions and the power of the engine.
Default values for the parameters are programmed
at the factory. Some parameters may be changed by
the customer in order to suit the needs of the specific
application.
Parameter Descriptions
“Equipment ID”
“Equipment ID” allows the customer to enter a
description into the Electronic Control Module (ECM)
in order to identify the machine. A maximum of
17 characters may be entered in the field. This
parameter is only for reference by the customer. This
parameter is not required.
“Top Engine Limit” (TEL)
Illustration 6
“TEL” is a customer programmable parameter that
defines the maximum allowable engine speed for
maximum power. “TEL” can be programmed up to
the maximum rated engine speed. “TEL” is defined
along the engine’s lug curve.
g00763900
“Engine Serial Number”
Program the “Engine Serial Number” to match the
engine serial number that is stamped on the engine
information plate. If the ECM is replaced, the engine
serial number from the engine information plate must
be programmed into the new ECM.
Note: When you are requesting factory passwords,
always use the engine serial number that is
programmed in the ECM.
“Rating Number”
The “Rating Number” corresponds to the selected
set of performance maps for the application. This
selected set of performance maps comes out of
several unique sets of maps that are resident in the
flash file. The dealer and/or the OEM will need to
select the appropriate rating tier, if more than one
rating tier is present. The rating tiers are A through E.
Note: Factory passwords are required in order to
change the “Rating Number”.
“Engine Accel. Rate”
“Engine Accel. Rate” determines the rate of change
of the engine speed (acceleration or deceleration)
during PTO operation. This rate of change is also
used to achieve intermediate engine speed.
“Low Idle Speed”
“Low Idle Speed” is the minimum allowable operating
speed for the engine. This parameter can be
programmed between 600 and 1400 rpm.
“PTO Mode”
“PTO Mode” allows the ECM to be programmed to
either one of the two PTO configurations that are
available.
“Ramp Up/Ramp Down” – When “PTO Mode” is
programmed to “Ramp Up/Ramp Down”, the ECM
allows PTO operation with traditional features.
“Set/Resume” – When “PTO Mode” is programmed
to “Set/Resume”, the ECM allows PTO operation with
enhanced features.
Page 21
RENR5042-0221
Troubleshooting Section
“High Idle S peed”
Illustration 7
“High Idle Speed” is the maximum no-load engine
speed when the throttle or the PTO switch is in the
maximum position.
g00763900
“Maximum Engine Torque Limit”
Illustration 8
“Engine Torque Limit” can be used to limit torque
output to the programmed value when the torque
limit switch is activated.
g00817759
Note: “High Idle Speed” cannot be programmed
lower than “TEL”.
“Intermediate Engine Speed”
“Intermediate Engine Speed” defines the speed
for the engine when the intermediate engine
speed switch is activated. This parameter can be
programmed to any engine speed between “Low Idle
Speed” and “TEL”. Engine speed will increase or
engine speed will decrease at the rate that is defined
by the programmed value for “Engine Accel. Rate”.
“Engine Power Trim”
This parameter cannot be changed.
“FLS” (Full Load Setting)
“FLS” is a number that represents the adjustment to
the fuel system that was made at the factory in order
to fine tune the fuel system. The correct value for
this parameter is stamped on the engine information
plate. Factory passwords are required in order to
change this parameter.
“FTS” (Full Torque Setting)
“FTS” is similar to “FLS”. Factory passwords are
required in order to change this parameter.
“Ether Control”
Program the “Ether Control” to “Enabled” if an
ether injection system is installed on the engine.
This allows the ECM to control ether injection. If
the engine is not equipped with ether, program this
parameter to “Disabled”.
“Air Shutoff ”
“Air Shutoff” allows the ECM to be programmed for
operation of an air shutoff system. If this parameter
is programmed to “Installed”, the ECM will activate
the air shutoff solenoid in the event of an engine
overspeed condition.

Monitoring System
The monitoring system determines the level of action
that is taken by the ECM in response to a condition
that can damage the engine. The monitoring of the

“Off”. These conditions are identified by the ECM
from the signals that are produced from the following

If the engine is cranking and Cat ET displays zero
rpm, a problem exists in the circuits for the engine
speed/timing sensors. Refer to Troubleshooting,
“Engine Speed/Timing Sensor Circuit - Test”.
If an engine speed is present, check the sensor
installation. If the sensor is not properly installed,
the ECM may read engine speed, but the ECM
cannot determine the tooth pattern. The ability for
the ECM to read the tooth pattern is necessary to
determine the cylinder position. Engine speed is
present when engine speed is greater than 50 rpm.
Refer to Troubleshooting, “Engine Speed/Timing
Sensor Circuit - Test”.
Electrical Connections to the Electronic
Unit Injector
1. Ensure that the electronic unit injector connector
(J300/P300) is fully connected and free of
corrosion.
2. Check for logged diagnostic codes that are related
to the cylinder. Refer to Troubleshooting, “Injector
Solenoid Circuit - Test” if diagnostic codes that are
related to the cylinder are present.

Example of the typical operating range of a temperature sensor
(1) This area represents the normal operating range of the
parameter. The normal output voltage of the s ensor is b etween
0.2 V DC and 4.2 VDC.
(2) In this area, the temperature above 107 °C (22 5 °F) is higher
than normal. The output voltage of the sensor will generate an
event code. The sensor does not have an electronic problem.
(3) In these areas, the output voltage of the sensor is too high
or too low. T he voltage is outside of the normal range. The
electronic problem will generate a diagnostic code. Refer to
Troubleshooting, “Troubleshooting with a Diagnostic Code” for
additional information on diagnostic codes.
Events are represented in two formats. In the first
format, the “E” means that the code is an event
code. The “XXX” represents a numeric identifier for
the event code. This is followed by a description of
the code. If a warning, a derate, or a shutdown is
applicable, the numeric identifiers are different. Refer
to the following example:
E004 Engine Overspeed Shutdown
•
In the second format, the “E” means that the code is
an event code. The “XXX-X” represents a numeric
identifier for the event code. The fourth “X” identifies
the event as a warning, a derate, or a shutdown. This
